25. // infer generics doesn't throw error but most compilers throw warnings. List<String> list = new ArrayList<String>(),removeList = new ArrayList<String>(); list.add("hey"); for(String string : list) { // list.remove(string) throws exception because you can't remove while iterating through a list unless your using an iterator. removeList.add(string); } // fix to make a new list and remove y collection from x list. list.remove(removeList); also in java 8 api under collections there is a new method that is called removeIf and with a interface with a boolean to check what object to return. your not going to get good java developers that can answer all these questions for cheap huehue.
